The broader San Francisco Bay Area can also claim Silicon Valley and its booming economy.

But the city itself is in trouble. Today, San Francisco hosts an estimated homeless population of 7,500 people. Affluent sections of the city have become dangerous with open-air drug use, tens of thousands of discarded needles, and, sadly, human feces.

Since 2011, there have been at least 118,352 reported instances of human fecal matter on city streets.

New mayor, London Breed, won election by promising to clean things up. However, conditions are the same or worse. Last year, the number of reports spiked to an all-time high at 28,084. In first quarter 2019, the pace continued with 6,676 instances of human waste in the public way.

We reached out to San Francisco Mayor London Breed for comment regarding our findings and the continued trajectory of the human waste problem. This column will be updated with any response or comment.

Graph showing year-over-year increases in the human waste challenge in San Francisco.

The city has taken steps to crack down on the crisis. Over the last year, the Department of Public Works instituted what the San Francisco Chronicle called a "Poop Patrol." Consisting of five teammates, the Chronicle estimated each employee earned a hefty $184,000 in pay, perquisites and pension benefits.

Using this payroll information, we quantified the taxpayer cost of each human waste case last year: $32.75. And that’s not including the sunk costs in trucks, fuel, and equipment such as the steam cleaning unit.

At the turn of the 20th century, San Francisco was called "The Paris of the West." Locals were more humble and self-titled San Francisco as the Golden City. Pardon the expression, but lately there has been a brownout in the Bay Area.

San Francisco politicians have been among the most vocal proponents of reducing inequality across the nation. That’s a noble endeavor, but perhaps, their struggle should start closer to home.
